Dwyer 2205 Offers

Features

• Easy to read gauge through undistorted plastic face permits viewing from far away
• Patented design provides quick response to pressure changes means no delay in assessing critical situations
• Durable and rugged housing and high-quality components combine to provide long service life and minimized down-time
• Bezel provides flange for flush mounting in panel
• Clear plastic face is highly resistant to breakage, and provides undistorted viewing of pointer and scale
• Precision litho-printed scale is accurate and easy to read
• Red tipped pointer of heat treated aluminum tubing is easy to see, and it is rigidly mounted on the helix shaft
• Pointer stops of molded rubber prevent pointer over-travel without damage
• "Wishbone" assembly provides mounting for helix, helix bearings and pointer shaft
• Jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix, and motion is damped with high viscosity silicone fluid
• Zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover
• O-ring seal provides pressure tightness
• Helix is precision made from an alloy of high magnetic permeability, and is mounted in jeweled bearings, it turns freely, following the magnetic field to move the pointer across the scale
• Calibrated range spring is flat spring steel
• Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates - It is locked and sealed in position with a sealing plate and retaining ring, and the diaphragm motion is restricted to prevent damage due to overpressure
• Die cast aluminum case is precision made and iridite-dipped to withstand 168 hour salt spray corrosion test
• Exterior finished in baked dark gray hammerloid
• Overload protection
• Blowout plug is comprised of a rubber plug on the rear which functions as a relief valve by unseating and venting the gauge interior when over pressure reaches approximately 25 psig (1.7 bar)
• Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages

Applications

• Filter monitoring
• Blower vacuum monitoring
• Fan pressure indication
• Duct, room or building pressures
